I wrote a script (attached) that converts the output of "tethereal -G

bit of tweaking, we _might_ be able to turn this into a protocol poster.
One problem is that it doesn't catch cases where dissector A explicitly calls dissector B, e.g. with "find_dissector()" and "call_dissector()". We could add a protocol ID number argument to "find_dissector()", and have "find_dissector()" build a table of protocols and subdissectors, for that.
It also doesn't handle heuristic dissectors - "tethereal -G" would need to dump the heuristic dissector tables as well.
